Cut-off scale of quantum gravity as a sign to unify interactions
Abstract
Dynamics of gravity interaction with matter at one-loop level of effective quantum field theory naturally sets the cut-off scale E in a sub-Planckian region through incorporating the gauge coupling constant α(E) and the reduced Planckian mass mpl into relation E mpl\,α(E)/(4π) numerically yielding E 1016 GeV. Such two scales are empirically inherent for an inflationary cosmology.
